of the United States, residing at Paterson, New Jersey,

have invented a certain new and useful improvement in Car-Underframes,of which the .following isa lull,

. clear, and exact description, such will enable others skilled intheiart to which it appertains to makoyand use the saine, referencebeing had to the accompanying drawings, forming part'ol" thisspecilication, in whichHs Figure l is a plan view of an undorlrameconstructed in accordance with my invention; Fig. 2..is a side olcvation thereof; Fig. 3 is a longitudinalsectional view taken through thecenter ofthe frame, Fig, It is a cross sectional View taken on the lineLl-llof Fig. l; and Fig. 5 is a cross sectional view taken'on the line 55 Tli larly toithe underlram'ing of cars.

The object 0f my invention is to provide an underrame which is of simpleconstruction but very strong. Referring to the drawings which representthe preferred yform of my invention, l designates the center sills whichare preferably I-beams and these sills may either be continuous orspliced adjacent the bolster by means of splice plates 2,' the latterconstruction being preferable. v l

The platform end sills 3 consist of channels having top cover plates 4connected to the upper flanges thereof. The end lsills consist o liangedmembersl 5 connected their outer ends to the side sills 6 and-at theirinner ends to the center sills l, said members being-of uniform depththroughout the major portion of .their length but increasing in depthadjacent the cen* v terlsillaas shown in Fig. 4.

The bolster' consists of two members, A spaced quite a distance fromeach other, as shown in Fi'g. l, each of said members consisting ofpairs of flanged diaphragins 7 placed back to back and connectedto thecenter sills and side sills and a tension platev 8 and compression plate9 connected to the flanges of said diaphragme.

' and to the side sills, as shown in Fig. 5.

' bolster member,` and to insure a very rigid construction I luse anadditional bottoni coverplate l3wl1icl1 extends from the insidebolstermember to the dra-lt sills, as shown'in Fig. 3. lThis additional coverplate is connectedvto the lower flanges of the center sills and nventionrelates to railroad cars and particuyis bent downwardly with the bottomcover plate ll and connected to the end flanges of the draft. sills l2,the compro ing underneath this cover plate The draft rigging casting 'ldprovided at its uppcrend with a flange l5 which rests on the insidelower llangos oi the center sills and said ca' ing is riveted to thewebs oi thc ccntcr sill and to the webs of the draft sills, as shown inFig. lt, a llangcd diaphragm lti being interposed between the centersills above said casting. Fillers 17 and a king-bolt casting .i8 areinterposed between the' center sills` internleliliato the bolstermembers, and flanged diaphragme lll are arranged between the centersills at the points where the bolster members are connected thereto.

ion plate ol the bolster members cxtcnd- Diagonally'extending braces 20are connected at;

their outor ends by gusset plates to the side sills an end sills, an lat their inner lends to the center sills and one of the bolsteriilclnbers. lransverscly extending lloor supports 2l are connected tothe side sills and center sills, and ldngitudinally extending stringere22 are connected to said lloor supports and to the end sill members 5."Extending from the end sill to the platform end sill are two parallelangles 23 and also two angles 24 arranged underneath the angles 23,

' the platiorn'l plate 25 being connected tothe angles 23.

'rlaving thus described my invention, what l claim as new and desire tosecure by Letters Patent is:

l. An underfrnme comprising center sills, drnlt sills connected tothelower sides of the center sills, and :l bottoni cover plate connected tothe center sills and ,bent downwardly underneath -the draft sills;substantially as le-i scribed'.

L. An underlrune comprising cellier sills, draft sills connected to theunderneath sides or' lhdconter sil nnd provided :it their ends withllanggos, :l bottom cover plate connected to the center sills and bentdownwardly to engage the end llnnges ol' the dl'ul't sills to which theyare conA nected; suhstzullizully :is described.

'Il An undcrfrnme consistingl ol' [lang-od conter sills, pressed metri!draft sillsconnccted to tho center sills :Ind having inclined end`ll:1llges. n bottom cover plato secured to the center sills :1nd tolthel inclined hongos ol' the draft sills, and n reinforcing' plateextending from the bolster lo the drnlt sills and being;- connected tothe ond llnng'es of. said draft sills and to the bottom cover plate forthe center' sills; substantially :is described.

l. An undel'l'rzlnle comprising llzlnged center sills having di" sillsconnected tov-the lower ilnllg'es lhcrcoffund n casting' resting' on thenzlug-cs ol" thecentor sills and riveted to the webs oi' sn'id sillsnndlto the draft sills; suhstzlntzllly :1s described,

All umlert'rnlnc comprising 1li-urged center sills having channel-swipeddraft. sills connected to the lower flanges thereof, the legs 0l' soldcbnnncl projecting; outwardly, :1nd :rl-ostina' connected to thev wellset' -thc center sills and drzli't sills; substantially ns described.

vt5. An under-frame comprising flanged center sills, channel-shapeddraft sills connected to the bottom flanges of the center sills withtheir flanges projecting outwardly, a casting hnvingi, 'n Flange whichrests onthe lower flanges of the center sills, said casting betingconnected to the webs of the center sills :ind draft siils, and :iflanged diaphragm arranged between the center sills above said casting;sub4 siuntizilly :is described.

7. An underfrninc comprising centerI sills, side sills, two bolstermembers spaced :ipzirtfrom eiieli other, each of said members consistingof pairs of flanged diaphragme lconnected to the center sills and sidesills, a. continuous tension piatte extending;l over the center sillsund connected to said diaphrng'ins, :ind :i continuous compression plateextendim.;l underneath the center sills und connected to said(linphrngms, theonter ends of said compression and tension platesbeing;- connected to tile side sills, and n center bearing castingsecured to :the center sills midway said bolster members; substantiallyas described.

8. An nnderframe comprising center sills, side sills and two parallelbolster members spaced spart :1nd connected to the .center sills .andside sills, sold center sills being spliced intermediate the bolstermembers; substantially :1s deseribed.

In testimony whereof I hereunto zltlx my signature in the presence oftwo witnesses, this 30th day of November 1.906.
